24-fps progressive media. The Avid system creates 24p media by combining (deinterlacing) two video fields into a single full, reconstructed frame. For NTSC film-to-tape transfers, the system creates 24p media by undoing the 2:3 pulldown inserted by the telecine process, removing the extra fields, and creating progressive frames.

25-fps progressive media. The Avid system creates 25p media by combining (deinterlacing) two video fields into a single full, reconstructed progressive frame.

One of the first composite videocassette formats, in which the composite signal is recorded onto 3/4-inch tape. Used for many years, particularly in field recording, the U-matic format is slowly being replaced by more advanced and lightweight systems.

A digital video system defined by the ITU-R 601 (CCIR-601) technical documentation. 4:2:2 refers to the comparative ratio of sampling of the three components of the video signal: luminance and two color channels.
